European researchers (in a consortium including partners from Germany, Hungary and Italy) have managed to work out how to store 500GB of data on a regular HD DVD or Blu-ray disc.

The Microholas project developed a micro-holographic recording technique, using nano-structures inside the disk rather than on the surface as in conventional optical storage systems. This allowed for an increase of the storage capacity far beyond the limits of today's red-laser DVDs and next-generation blue-laser discs.
